After the tango show we walked down 9 de Julio, the big 18-lane avenue. At the obelisk there was quite a gathering of soccer fans – the Boca Juniors had just defeated the Tigre team for the championship. Fans were swarming to join the party; cops were on high alert. Fireworks and lots of chanting and singing and all the cars honking their horns. It looked like it was quickly developing into quite a party.
